To all whom it may concern:

Be it known that I,'WILLIAM' M. DEIOHLER, a citizen of the UnitedStates,residing at Lancaster, county of Lancaster, State of Pennsylvania, haveinvented certain Im provements in Apparatus for Sterilizing andFiltering Iiiq uids, of which the followingisa specification. Thisinvention: relates more-particularly to improvements in apparatus forsterilizing andf filtering water; and the objects of my improvementsare, first, to cut out the filter from or bring it into the'course takenby the water in:

passing from the sterilizing apparatus to the receiving-tank; second, tocleanse the filtering medium of impurities removed thereby from thewater pas'singthrough it, and,thi rd, j

A device for carrying my invention into eitect is illustrated in theaccompanying drawings, forming a part of this specification, wherein-Figure 1 is a perspective yiew of a con-' struction embodying myinvention; and 'Fig. 2, a side elevation of the same, parts" being insection to show the operation of the mechanism. r

Similar letters indicate like parts throughout the two views.

Referring to the details of the drawing,A

indicates a pipe forming the means;through:

which the original supply of water' is furi nished and which feeds intoa'cooling-tank B,

to be further described, said pipe A having a stop-cock at. The waterpasses through cooling-tank B' toand through a pipe Z entering the upperend of a sterilizing-boiler D and extending nearly to the bottomthereof. The bottom of boiler D is connected by a pipe 01 with the lowerportion of a water-back E, surrounding or connected with a stove orheater E. Above the entrance of pipe dinto water-back E a pipe Eentersand connects said water-back with boiler D above the bottom ofpipe I). From water-back D, wherein the water is boiledfthe course ofthe same is through pipe E into sterilizing-boiler D, thence upwardthrough said boiler D to and Ethrough'a pipe F, connecting the upper endof said boiler and the upper end of a coolingcoil G, located incooling-tank B, and thence downward through said cooling-coil and out ofsaid tank into an upwardly-extending pipe .H,'=havinga horizontalsection H, through which pipe H H itis conveyed and'disc'harged into thetop of a filter I, there being a stopcock-h' in section H of pipe-H IIand adjacent to the filter. The sterilized water is filtered as itpasses down through the filter to the discharge-pipe 1", through whichit is fed to pipe K, by which the water is conveyed to the point whereit is discharged into the receiving-tank. 'Onthe discharge end of pipefK is' asp'rayer K-,where by the water is aerated by spraying the sameinto the receiving-tank. (Not shown, as it forms no part of thisinvention) In pipe I there is a stop-cock 2', located adjacent to'thefilter, pipe K also having a stop-cock K Thewater is' sterilized byboiling in the Water-back and boiler D, on

. other suitable means be used for heating the .Wate'rto a suitabledegree in said boiler D.

Cooling-tank .B has'a twofold action-the sterilized water is cooled asit passes downward through coil G and the heating of the unsterilizedwater is begun as it passes up .ward through and around the convolutionsof coil G, It is held by scientists that water should .be boiled notless than fifteen minutes to thoroughly sterilize the same; but in my-sterilizing and filtering device the proportions of the constructionare such that the water will be boiled for an hour or upward, the lengthof time being modified by the amount of water drawn on and the pressureof the ICO of an upright cleaning-pipe N is connected with pipe M beyondthe filter, and the upper end of said pipe N is connected with the upperend of the filter, near which end of pipe N is a stop-cock n. There isalso a stop-cock m in pipe M and located between pipe M and pipe L, anda stop-cock m in said pipe M and located between pipe M and pipe N.Stopcocks a, h, 1 and K are normally open, while stop-cocks m, m, and nare normally closed. To cleanse the filter, stop-cocks h and i areclosed and stop-cocks m and n are opened, and to remove any sedimentfrom the bottom of the filter stop-cock z' is closed and stopcock mopened.

Section H of pipe H H and discharge-pipe I are connected by a verticalpipe P, located outside of stop-cocks h and i and having therein astop-cock p, which is normally closed. This pipe P permits the filter tobe cut out of the course taken by the Water, so that the same can besupplied directly from the sterilizer to the tank. For this purposestop-cocks h and c' are closed and stop-cock 1) opened.

I do not restrict myself to the details of the construction herein shownand described, as it is obvious that numerous alterations can be madetherein without departing from the principle and scope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, in an apparatus of the character described, of asterilizer, a filter, a pipe extending from the sterilizer to thefilter,

a stop-cock in said pipe, a discharge-pipe attached to the filter, astop-cock in the discharge-pipe, a pipe beneath the filter and connectedwith the pipe extending from the sterilizer to the filter and betweenthe stop-cock therein and the sterilizer, a connection between thebottom of the filter and the pipe beneath said filter, a stop-cock inthe pipe beneath the filter and located between the filter and theconnection of said pipe with the pipe extending from the sterilizer tothe filter, a cleaning-pipe connected with the top of the filter, and astop-cock in the cleaning-pipe, for the purpose specified.

2. The combination, in an apparatus of the character described, of asterilizer, a filter, a pipe extending from the sterilizer to thefilter, a stop-cock in said pipe, a discharge-pipe attached to thefilter, a stop-cock in the discharge-pipe, a pipe beneath the filter andconnected with the pipe extending from the sterilizer to the filter andbetween the stop-cock therein and the sterilizer, a connection betweenthe bottom of the filter and the pipe beneath said filter, stop-cocks inthe pipes beneath the filter, one of said stop-cocks being located oneach side of the connection between said pipe and the bottom of thefilter, a cleaning-pipe connected with the top of the filter, and astop-cock in the cleaning-pipe, for the purpose specified.
